Why did the school escorts invented by Porfirio Díaz promote discrimination against students in Mexico?

The school escort ritual in Mexico, established over a century ago during the Porfirio Díaz era, has been identified as a mechanism for student discrimination. The practice transformed a civic ceremony into a selective process based on academic performance, where a student's grade point average determined their eligibility to represent the country in formal school events.

This system effectively created a divide between students, as those with lower grades were excluded from participating in the patriotic ritual. By tying civic representation to academic achievement, the historical institution established a standard that prioritized specific performance metrics over inclusive participation in national ceremonies.
